HAND-GRIP FOR TELEPION-STANDARDS.

To all whom it may concern u i Be it lmown that I, JOHN HARRISON, a citizen of the UnitedV States, residing at Philadelphia, in the county of Philadelphia and btate of Pennsylvania, have invented certain new and useful Improvements in Hand Grips for Telephone Standards, of which the following is a specification.

My invention relates to improvements in hand grips for telephone standards, the 0bject of the invention being to provide a grip of the character stated which can be readily positioned on any telephone standard, and which will prevent Contact of the hand with the metal of the standard which will act as an insulator to prevent any possibility of the hand receiving an electric shock, and which will not disfigurethe telephone or interfere with its ordinary functions.

A further object is to provide a grip of the character stated composed preferably of rubber or other non-conducting flexible or elastic material having springs embedded in the material and operating to clamp the grip around the standard, so that it can be readily placed in position or removed as desired. j

` Vith these and other objects in View, the vinvention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure l is a view in side elevation illustrating a desk telephone of the ordinary type provided grip. Fig. 2 is a view in cross section on the line 2-2 of Fig. l showing the spring embedded in the material of the grip in elevation, and Fig. 3 is a perspective view illustrating the clamping springs in full lines and the grip in dotted lines.

My improved grip comprises a split cylinder l having at its lower end a split base 2. The base and the cylindrical casing conforming in shape to the base 3 and standard et of an ordinary telephone and having an offset portion 5 at the juncture of the casino' and the base to conform in shape to the ordinary telephone.

As aoove stated, the casing l of the base 2, is split, and at the split portion, the

ase 2 is recessed as shown at 6 to accommodate the wires 7 which extend into the base 3 of. the telephone standard.

Specification' of Letters Patent.

Application led July 1, 1914.

serial Nb. 848,339.

Within the `material of casing l, I embed springs 8. These springs are composed prefof strips of spring metal, circular in with their ends terminating short of the edges of the casing so that in positioning the grip standard 4, the casing and the. base portion 2 can be opened at the split sufficiently to allow the same to receive the standard, and when the standard is in place and the gri released, the springs 8 will tightly bind the grip around the outside of the standard and hold the same in place.

The grip is preferably of rubber, although may use other flexible resilient and non conducting material. The springs 8 are molded in the material of the grip, and are inclosed in said material, so that they do not contact with the standard of the telephone, yet give to the grip the necessary elasticity to tightly hold the same upon the standard.

hen in use, the operator grasps the grip and his hand is entirely insulated from the standard and protected from any metal of the standard which might be injurious to him. As the base portion 2 of the grip eX- tends over the base 3 of the telephone standard, the hand is protected from the metal of the base as well as from the metal of the standard and in fact, the grip operates as an efiicient protection against injury to the hand either by electric shocks or by reason of contact with metal of some sort.

Various slight changes might be made in the general form and arrangement of parts described without de Jarting from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A grip of the prising a cylindrical material adapted to character stated, comsplit casing of elastic be sprung to position around the standard of a telephone, said casing at one end having a fiared base p0rtion adapted to be positioned over and cover the upper portion of the base of the telephone, substantially as described.

2. A grip of the character stated, comprising a cylindrical casing and base coInposed of flexible non-conducting material, said casing and base split throughout their "Patented Dec. 2a, 191e.
